Optimization of Aeroengine Robust Controller Based on Adaptive Simulated Annealing Genetic Algorithm

In this paper, the H∞ robust controller is designed based on dual external variable cycle engine with core driven fan stage. The objective function is to calculate according to the performance requirements of the aeroengine control system, and the weight function matrix of the controller is optimized by the adaptive simulated annealing genetic algorithm. The H∞ robust controller based on adaptive simulated annealing genetic algorithm for variable cycle engine is designed to avoid the drawbacks that the traditional method relies heavily on the designer’s insufficient experience when selecting the weight function matrix, and solve the problem that it is time-consuming and laborious to select the weight function matrix through repeated tests. The simulation results of the nominal points and the selected points in the flight envelope show that this method can make the control system obtain better robust stability and robust performance, as well as strong anti-interference ability.
